Make those microbes warm up water. Pupils first investigate water pumps, then design a water circulation system that uses solar energy. A bioreactor in the system takes energy from compost and helps heat water.

Now you have a new excuse not to do your homework. A long-term experiment has learners explore cellulose-digesting enzymes. They simulate how paper breaks down in a compost bin. There's no need to blame your dog for eating your homework...

Young biologists trace the path of the sun's energy through marine ecosystems in the second part of this four-lesson series. Building on prior knowledge about producers, consumers, and decomposers students are introduced to the...

Students isolate and determine the amount of plasticizer in polyvinyl chloride. They use Infrared Spectroscopy (IR) or Fourier Transform Infrared Spectroscopy (FTIR) and gravimetric techniques in this experiment.

In this chemistry worksheet, students determine the order of reactivity toward displacement in each of the series listed. Then they respond to several multiple choice questions as they relate to compounds and solutions. Students also...

In this chemistry worksheet, students focus upon the solving of the chemistry equations. The elements are given and then combined.

Students investigate how organic matter increases the amount of water soil will hold. In this water soil lesson plan, students use soil and measure water amounts using organic matter. Students measure the water holding capacities.

Learners discuss food and the food groups and their organic nature. They test 3 different solutions and test for protein, starch and glucose. In addition, they create a master table on the board to collect all the teams results.

Students recognize the presence of organic matter in soils from their immediate area and recognize which soil sample contains the highest concentration of organic matter.

Students explore how coal is formed. They then discuss the information and answer any questions that they may have on the formation of coal. Students then answer questions in reference to the coal discussion and reading.

Students examine soil samples for the presence of organic matter. They determine which soil sample from their area contains the highest amount of organic matter.
